Yahoo YUI 2 - Rich Text Editor - can't get setEditorHTML method to work, what's wrong?

Today, for the first time, I came across the YUI 2 Rich Text Editor. (http://developer.yahoo.com/yui/editor/)

Today, for the first time, I came across the YUI 2 Rich Text Editor. (http://developer.yahoo.com/yui/editor/)

I mainly use Java Server Pages for my websites.

I want to be able to set the text in the textarea of the Editor to a previously submitted value. As an example, when a user submits the page, after having entered text in the Editor, that text may be saved in a database for future use. I would then call the value from the database, and set the Editor to display it at that point, so the user could make modifications.

I found a method in the API documentation called setEditorHTML() - but for some reason or another, I can't get it to work.

Here is the test code I've been playing around with. I'm testing in Firefox.

I don't understand why the setEditorHTML method won't work...can someone please assist me?

<% String editorText = (String)session.getAttribute("editorText"); %>

There is a time while the editor is rendering which you cannot access setEditorHTML. Try this:

var myEditor = new YAHOO.widget.Editor('msgpost', {
    height: '300px',
    width: '522px',
    dompath: false, //Turns on the bar at the bottom
    animate: false, //Animates the opening, closing and moving of Editor windows
    handleSubmit: true
});

myEditor.render();
// I just took a guess on which event to use here
myEditor.on('windowRender', function() {
    myEditor.setEditorHTML("Hello World");

});
